OUR SAND CASTINGS
Sand Casting Manufacturer in Mumbai - Up to 200 Kgs
Capacity
Our sand casting facility in Mumbai (Goregaon) manufactures high-quality
stainless steel, alloy steel, and carbon steel castings up to 200 Kgs single piece
weight using the CO2 (Sodium Silicate)
moulding process.
Casting Weight Range
We manufacture:
- Sand Castings up to 200 Kgs
- Medium to heavy industrial components
- We specialize in custom manufacturing of sand castings strictly as per client drawings,
approved patterns, and technical specifications.
- Precision-engineered components.
Our facility is equipped to handle both small batch and regular production requirements.
Our Sand Casting Process (CO2 Process)We use
high-grade silica sand moulds hardened through the CO2 process, which ensures:
- Strong and rigid mould structure
- Excellent dimensional accuracy
- Good surface finish
- Reduced shrinkage and defects
- Reliable metallurgical consistency
This process is ideal for producing durable industrial castings with consistent quality.
Grinding & Fettling Facility for Sand Castings
At our foundry i, we maintain a dedicated in-house grinding and fettling facility to
ensure every sand casting meets dimensional accuracy and surface finish requirements before
dispatch.
Our Capabilities Include:
- Removal of gates, risers, and excess material
- Surface grinding and finishing
- Burr removal and edge smoothing
- Cleaning of casting surfaces
- Visual inspection after fettling
- Preparation for machining (through our trusted machining vendors)
Why Our In-House Grinding Matters
- Better quality control
- Faster turnaround time
- Reduced rejection rate
- Consistent surface finish
- Ready-to-machine castings
We handle Austenitic, Martensitic, Duplex, Super Duplex and Heat Resistant Steel
Castings with strict quality checks at every stage.
OUR CENTRIFUGAL CASTINGS
We specialize in high-quality centrifugal castings manufactured using precision
centrifugal dies. Our facility is equipped with dies ranging from 123 mm Outer Diameter (OD)
up to 338 mm OD, with lengths up to 660 mm.
Centrifugal casting ensures:
- Superior mechanical strength
- Dense, porosity-free structure
- Uniform grain distribution
- Excellent performance in pressure and wear applications
These castings are ideal for bushes, sleeves, pipes, liners, and cylindrical
components used in industrial applications.

Finished Wear Rings
We specialize in manufacturing Finished Wear Rings in all Austenitic, Martensitic,
and Duplex steel grades suitable for various types of pumps.
With a strong focus on metallurgical integrity, dimensional accuracy, and surface finish, our wear
rings are produced to meet precise pump OEM specifications and performance requirements.
We work with experienced and well-developed machining contractors who enable us to deliver fully
finished and ready-to-fit components with consistent accuracy and quality.
In-House Heat Treatment & Quality Assurance
All castings are supplied duly heat treated in our advanced in-house heat treatment
facility equipped with:
- Hardening Furnace [1200 °C Temp.]
- Tempering Furnace [750 °C Temp.
- Graph-based temperature monitoring & recording systems
- Water Quenching Tank of 3000 Ltr. Capacity for Solution Annealing.
- We also do have a BHN Hardness Testing Machine .
